SNCF currently operate all domestic services in France. The Intercite medium distance services are sponsored by the government, and the local TER services by the regions. SNCF is keen for customers to do everything on-line from train enquiries to ticket purchase, with tickets downloaded onto a smart-phone. There are fewer guichets, where you can buy tickets over the counter and most have a long wait. Some cheaper services Ouigo
and Intercite Eco
can only be booked on-line. The once common paper timetables for each route have now largely been discontinued, although still produced by a few TERs.
The SNCF journey planner https://www.voyages-sncf.com
is far from user-friendly. Drawbacks include time of day parameters that are too narrow, and the refusal of the system to accept a journey with more than two changes. It has a strong preference for SNCF TGV services, even if this involves a circuitous route.
The best point-to-point on-line 'journey planner' timetable is the Deutsche Bahn HAFAS Europe-wide timetable database. It can be accessed in English or French, although the original German is fairly self-explanatory.
Traditional timetables can be downloaded from the ‘Horaires & Trafic and Fiches Horaires’ section of individual TER sites.
There is normally a drop down box in the ‘Ligne’ section showing the tables available in pdf format. These also normally show Inter-cites services operating over TER routes. Given SNCF’s practice of suspending train services for engineering work it is is prudent to also check via a journey planner or the relevant ‘Travaux’ section. The link below is to the main TER site from which individual regions can be selected. http://www.sncf.com/fr/trains/ter
If the required table is not available it might be found by selecting an individual station site (put SNCF and station name into google) as these also have links to relevant pdf tables.
